Is there a find/replace names
You can try Proxe's addon here https://github.com/trentinfrederick/name-panel
and see if it will work for you. It is supposed to support batch renaming, so maybe that could work.

Edit: I will try to get some working examples in picture form tonight and update here.- craigo

  Summary
  
  This add-on allows for batch naming operations and displays object datablock names in a single panel within the 3D view, don't take my word for it though, check it out
  
  The whole goal behind this add-on is to consolidate names and naming operations, while granting fast access to a few options here and there, I hope that this add-on saves you a lot of time.
  
  Overview
  
  This addon offers a panel that displays object related datablock names below the object and object data name fields, offering quick access within the 3D View to all available datablock names, along with an occasional option or few, like a mini outliner, filter options are located towards the top of the panel and the panel itself is located in the properties shelf of the 3D view and in addition this add-on comes with a series of operators that save a lot of time when renaming datablocks, the operators are as follows;
  
  Auto Name
  
  This operator allows for quickly naming objects and those object's modifiers, constraints, object data and for pose bones, bone constraints. It works by assigning names based on type, the names used are defined by the user and can be saved with user settings. (Options saved with the current scene)
  
  Batch Name
  
  This operator is the big work horse here, through its various toggle options and input fields you are able to perform find and replace text operations (with regular expression support) to almost all datablock names in the file and control how duplicate names will be numbered. The pop-up is a bit clustered but is fairly straightforward to understand once you use it a time or two, the tool-tips indicate what the option is doing/allowing.
  
  Note - This operator can be accessed either through the item panel special menu or in the outliner header, it can be called from any window type, just search 'batch'
  
  Batch Name Copy
  
  This operator is meant to fulfil the need to transfer names from some object datablocks to others, essentially copying them and pasting to the targets, this is done on a per object basis unless the 'use active object' option is active, which will then transfer the source name from the active object to the selected objects.
  
  WARNING! - By default all three operators DO NOTHING, you MUST activate the appropriate filters in the operator's pop-up

  WARNING AGAIN! - By default all three operators DO NOTHING, you MUST activate the appropriate filters in the operator's pop-up."
